Up-to-date figures on early losses of Thoroughbreds from the racing industry can inform strategies to improve retention and incentivise traceability of Thoroughbreds during this early life period.
Data on Thoroughbred mares bred in 2013-2014 and training, racing and sales information of their live offspring were analysed. The proportions and 95% confidence intervals (95% CI) of the entire 2014-2015 United Kingdom and Ireland foal crops that entered training, raced, were imported and/or exported between birth and the end of their third year of life, as well as the racing performance of these horses as 2- and 3-year-olds were described.
A total of 20,661 mares produced 28,282 live foals. Of them, 47.2% (95% CI: 46.7-47.8; n = 13,354) entered training by the end of their third year of life. Of these, 10,595 (79.3%; 95% CI: 78.7-80.0) raced at least once. Around 20% (n = 5712) of horses were exported by the end of their third year of life, of which 3526 (61.7%) had been in training. The overall mortality during the study period was 7.6% (n = 2123).
A considerable proportion of Thoroughbreds had not entered training by 3 years of age but of those that had, the proportion that raced at least once was high. Further research is needed to establish reasons for premature losses from the industry.
最新的关于赛马行业早期淘汰的纯血马数据可以为改进保留率提供信息，并在这个早期生命阶段激励对纯血马的溯源。
分析了 2013-2014 年繁殖的纯血母马及其活驹的训练、比赛和销售信息。描述了整个 2014-2015 年英国和爱尔兰的马驹数量，包括进入训练、比赛、进口和/或出口以及在 3 岁生日前的第三年结束时的出口情况，以及这些马在 2 岁和 3 岁时的比赛表现。
共有 20661 匹母马生产了 28282 匹活驹。其中，47.2%（95%CI：46.7-47.8；n=13354）在 3 岁生日前进入训练。其中，10595 匹（79.3%；95%CI：78.7-80.0）至少比赛过一次。到 3 岁生日时，约有 20%（n=5712）的马被出口，其中 3526 匹（61.7%）在训练中。在研究期间，总死亡率为 7.6%（n=2123）。
相当一部分纯血马在 3 岁之前没有进入训练，但在进入训练的马中，至少比赛过一次的比例很高。需要进一步研究以确定行业早期淘汰的原因。
